Social Media Canvases for PowerPoint

For years, PowerPoint has been synonymous with boardroom presentations and academic lectures. Its default 16:9 slide ratio is tuned for projection screens, not LinkedIn grids or TikTok thumbnails. But what if the same tool that powers your pitch decks could also become your go-to design app for social media content?

Enter the Social Media Canvas add-in for PowerPoint on Windows —a lightweight, intuitive extension that transforms PowerPoint into a rapid-fire graphics engine for content creators.

What’s your social?

Do you book the face, tick the tok, or just like everything in an insta? Whatever your favourite social media platforms, you know that time is precious and getting your ideas out there quickly can be the difference between being a leader or a follower. But you might not turn to PowerPoint as your chosen design app because it’s synonymous with creating presentations. Don’t diss it yet. Read on. You might be surprised.

What’s the problem?

As a presentation-centric app, PowerPoint offers a few canvas sizes which steer you towards the presentation creation process:

Can you see where to select the canvas sizes for your next social media post? No! Now where you can do it? You first need to go and find the pixel size, do some math, and fiddle around with this dialog to get things just right. And let’s be honest, this does not sound like a great use of content creation time.

Enter the Social Media Canvas add-in for PowerPoint!

Put simply, this add-in gives you a brand new workflow for creating your social media content. Start where you normally create new files from, the backstage view – which, incidentally, is only supported by Microsoft PowerPoint on Windows – you get here simply by pressing File in the ribbon. Then click the Social Media tab to get started with your new creation:

From here, you can choose the social media platform you want to design for, and then choose the type of content you’re going to create. If you can’t find the exact size you’re looking for you can create a bespoke size by clicking the Custom Size button at the end of the list of social media platforms.

When you’re happy with your choice, click the Create New File button and a brand new file will be generated, at the right size, ready for you to start designing. And this is where the power in PowerPoint comes to the rescue. It’s so easy to drop pictures, text, video and other content exactly where you want on your canvas. You then have a smorgasbord of in-app tools to align and edit that content to your heart’s desire. We have a ton of articles about creating content in PowerPoint in our blog.

Once you’ve finished designing, come back to the File / Social Media tab and choose Save as Pictures. This guarantees that your slides are exported as PNG images at precisely the right number of pixels for the chosen canvas size.

And if you’re creating video content (did you know PowerPoint can create videos too?) then you can also export as an MP4 video by clicking the Create a Video button. You even get to choose the frame rate and compression quality level.

In addition to the new file setup experience, you’ll also find a new menu in the Design tab of the PowerPoint ribbon:

This menu provides a quick way to modify the size of an existing file, without modifying your original content.

Why is it free?

At BrightCarbon, we have two Microsoft MVPs (Most Valuable Professionals). The program is deeply rooted in community and as such, MVPs give up a portion of their time to create content to serve their chosen specialised area. For some years I’ve listened to people saying “Wouldn’t it be cool if PowerPoint could do XYZ?” and this was one of those examples where I thought an add-in could fill a gap. So this is a gift from me to you, supported by BrightCarbon. I hope you enjoy using it and we’d love to see some examples of what you manage to create with it.
